What Is Tear Trough Deformity?
Posted Champagne On Ice – Deep Cleansing [post_date] [post_comments] [post_edit]
Tear trough deformity is the clinical term for a hollow, shadowed groove that runs from the inner corner of the eye downward and outward toward the cheek. It’s one of the most common cosmetic concerns we see at Centre for Surgery — and one of the most misunderstood, because patients often confuse it with under-eye bags, dark circles, or general "tired eyes." These are related but anatomically distinct findings, and each one requires a different treatment.
This guide explains what tear trough deformity actually is, why it develops, how to distinguish it from other under-eye concerns, and what the realistic treatment options are.
What the tear trough actually is
The tear trough is a natural anatomical feature. It’s the depression that marks the transition between the lower eyelid (which sits on a thin membrane over the eye) and the cheek (which sits on a substantial fat pad). In youthful faces, this transition is smooth — the cheek fat is full and high, and the lid blends invisibly into it. The "tear trough" exists anatomically but isn’t visible.
Tear trough deformity develops when that smooth transition becomes a visible groove or hollow. Several anatomical changes contribute:
Loss of mid-face fat volume. The cheek fat pads thin and descend with age. The cheek that used to sit high under the eye now sits lower, and the lid-cheek junction becomes visible as a shadowed line.
Bony orbital rim changes. The bone around the eye socket actually changes shape with age — the lower rim resorbs slightly, creating a small step where the lid meets the cheek.
Skin thinning. The skin over the lower lid is around 0.5mm thick — the thinnest on the body. As it thins further with age, underlying structures (blood vessels, the underlying muscle) become visible through it, contributing to dark shadowing.
Tethering at the orbital rim. The lower lid is firmly anchored to the bone of the orbital rim by ligaments. As the cheek tissue descends with age, the lid stays in place — and a visible step or groove forms at the tethering point.
Negative orbital vector. Some patients are born with a bony anatomy where the eye sits forward of the cheek (rather than the cheek projecting forward of the eye). This anatomy — called negative vector — produces a pronounced tear trough deformity even in young patients, and it influences which treatments are appropriate.

What causes it to develop or worsen
Ageing is the most common cause. Volume loss, bony changes, skin thinning, and skin laxity all progress over decades.
Genetics determine the baseline anatomy. Some patients are born with prominent tear troughs that become visible in their twenties; others develop them only in their fifties.
Significant weight loss can produce visible tear trough deformity at any age. Rapid loss of facial fat depletes the cheek volume that previously concealed the lid-cheek junction.
Chronic stress and poor sleep contribute through multiple mechanisms — vascular changes, fluid retention patterns, and inflammation that affects skin quality.
Sun exposure accelerates collagen and elastin breakdown, contributing to skin thinning and quality changes around the eye.
Smoking compounds the problem with direct collagen damage and vascular compromise.
Allergies and chronic eye conditions can contribute to swelling cycles that exaggerate the under-eye appearance.
Tear trough vs. under-eye bags vs. dark circles
These three findings often coexist but they’re not the same thing, and confusing them leads to inappropriate treatment.
Tear trough deformity is a hollow or depression. It produces shadowing because light doesn’t reach into the groove. The under-eye area looks sunken or "in."
Under-eye bags are protrusions. They’re caused by orbital fat herniating forward through a weakening septum (the membrane that holds the fat behind the eye in place). The under-eye area looks raised or "out." For more, see how to get rid of under-eye bags and can eye bags go away?
Dark circles are a discolouration of the under-eye skin. They can be caused by shadowing from a deep tear trough, by pigmentation from sun exposure or genetics, by vascular show-through (blood vessels visible through thin skin), or by chronic inflammation. See our guide on bags under the eyes and dark circles.
It’s possible to have all three at once — many patients do. But they need different treatments:

Treatment options for tear trough deformity
For most patients with isolated tear trough deformity, hyaluronic acid filler is the standard non-surgical treatment. The product is placed deep, onto the bony orbital rim, to fill the hollow from below — restoring the smooth transition between lid and cheek.
The product choice matters significantly. The under-eye area requires a specific kind of HA filler — soft, with low water-binding capacity, designed for placement under thin skin. Standard cheek or lip fillers are too robust for this area. At Centre for Surgery the standard choice is Teosyal Puresense Redensity 2, which is formulated specifically for the periorbital area. Read more about how long results last in our guide on how long do tear trough fillers last.
Results are typically visible immediately and last 6 to 12 months on a first treatment. The treatment is reversible with hyalase if needed.
For patients whose tear trough is secondary to descended cheek volume, cheek filler is often more effective than tear trough filler. Restoring the volume above the lid-cheek junction lifts the descended tissue back to where it sat in youth, and the tear trough hollow softens indirectly — sometimes without needing any filler in the trough itself.
This is particularly true for patients in their 30s and early 40s where the underlying anatomy is intact but mid-face descent has begun. The cheek approach produces a more natural-looking result than chasing the hollow directly.
Facial fat transfer uses the patient’s own fat — harvested from another area of the body — to fill the tear trough. Unlike HA filler, the result is permanent for the fraction of fat that survives transfer (typically 50 to 70%). The transferred fat integrates fully with surrounding tissue and produces a softer, more natural-looking result than synthetic filler in selected cases.
Fat transfer is particularly useful for patients with significant volume loss across the mid-face, or for those wanting a long-lasting result. It’s often combined with blepharoplasty when both volume loss and skin or fat changes are present.
Lower blepharoplasty is the surgical procedure that addresses excess lower lid skin and herniated orbital fat — the structural changes that filler cannot address. For patients whose under-eye concerns include true bags, significant skin laxity, or festoons, blepharoplasty is the appropriate intervention rather than continued filler treatment.
A specific variation — fat repositioning blepharoplasty — uses the herniated orbital fat from the bag to fill the tear trough below, addressing both findings in a single procedure. This is a more sophisticated technique than simple fat removal and produces excellent results in the right hands.
The procedure takes 1.5 to 2 hours and requires about a week of social downtime. Results are long-lasting and look natural when performed by experienced surgeons.
For patients also considering surgical correction of the upper eyelid, full blepharoplasty addresses both upper and lower lid concerns in a single procedure.
For patients whose primary complaint is skin quality, pigmentation, or fine lines around the eye rather than the structural hollow itself, energy-based treatments may be more appropriate than filler.
SmoothEye laser stimulates collagen and improves skin quality in the periorbital area. Morpheus8 radiofrequency microneedling reaches deeper into the dermis for stronger tightening. Both treatments can be combined with filler when both structural and skin-quality concerns are present.
Who is a good candidate for tear trough filler?
The ideal candidate has:
A useful self-test: pull the skin below your eye gently downward with a fingertip. If the hollow becomes less visible when the skin is stretched, filler is likely to help. If the hollow remains visible regardless, or if there’s clearly herniated fat sitting above the trough, filler isn’t the right answer.
Candidates for surgical correction (fat transfer or blepharoplasty) should additionally be physically and mentally healthy, non-smokers or willing to stop smoking before surgery, and have realistic expectations about recovery and outcome.
A consultation with our specialist team — including Dr Spyridon Vlachos — establishes which category fits your anatomy and what the right intervention is.
Risks and complications
Filler complications include bruising, swelling, asymmetry, lump formation, migration, and chronic puffiness from old undissolved product. The most serious — though rare — complication is vascular occlusion, which can cause skin necrosis or, in extreme cases involving facial arteries connecting to the eye, vision changes. This is why tear trough filler should only be performed by practitioners with detailed anatomical knowledge and immediate access to dissolving treatment.
Filler complications worth knowing about that develop later (over weeks rather than immediately) include worsening bruising, worsening redness or swelling, persistent loss of sensation, severe pain, infection, or blurry vision. Any of these require urgent assessment.
Surgical complications include hematoma, infection, asymmetry, scarring, dry eyes, vision changes, and unsatisfactory aesthetic results. These risks are low in experienced hands but cannot be reduced to zero by any technique.
Fat transfer specific risks include overcorrection, asymmetry, lumpiness, and partial absorption requiring touch-up treatment.
A thorough consultation explains the realistic risk profile for the specific procedure you’re considering.
What home remedies and lifestyle changes can achieve
Patients often ask about natural approaches. The honest answer:
Daily SPF, good sleep, hydration, and not smoking slow the progression of tear trough deformity but don’t reverse what’s already established.
Topical skincare (retinoids, vitamin C, niacinamide) improves skin quality and can lighten pigmentation contributing to dark circles, but doesn’t change the structural hollow.
Cold compresses reduce temporary puffiness but don’t change underlying anatomy.
Drinking water matters for overall skin quality but won’t eliminate established tear troughs.
Concealer and highlighting makeup can effectively camouflage the appearance for daily use without any intervention required. For many patients, this is the right answer.
For patients wanting structural correction, the realistic options remain filler, fat transfer, or surgery — depending on which anatomical changes are present.
Cost
Tear trough filler is priced per syringe of Teosyal Redensity 2. Most patients need 1 syringe for the initial treatment with a possible top-up at 2 to 4 weeks. Surgical options vary substantially. Finance options through Chrysalis Finance, including 0% APR, are available.
Common questions
Most people develop some degree of tear trough deformity with age, but the timing and severity vary enormously based on genetics, lifestyle, and bony anatomy. Some patients have visible tear troughs in their twenties; others reach their fifties without significant changes.
No. Once established, tear trough deformity tends to progress slowly with age rather than improving. The good news is that the change is gradual — and the available treatments work well for the right candidates.
Retinol improves skin quality and may reduce fine lines around the eye, but doesn’t address the structural hollow that defines tear trough deformity. It’s a useful component of overall skincare but not a treatment for the deformity itself.
Patients with malar oedema (chronic lymphatic puffiness producing festoons) should not have filler — the product accumulates with fluid and creates permanent puffiness. Patients with body dysmorphic concerns about the eye area rarely achieve satisfaction with treatment. Pregnancy and breastfeeding are reasons to delay any elective treatment. See our guide on why under-eye filler is not for everyone for the full discussion.
Look in a mirror at neutral expression. Tear troughs are hollows — the area below your lid looks darker or indented compared to your cheek. Bags are protrusions — the area below your lid looks raised or pouchy compared to your cheek. Many patients have both. The two need different treatments.
Hydration affects how the area looks day-to-day (well-hydrated skin reflects light more evenly), but it doesn’t reverse the structural changes that produce tear trough deformity. Sufficient water is part of good skin health, but it isn’t a treatment.
